Where clinical precision meets effortless beauty — a brand built by a nurse, for every woman.
Born from Passion, Built on Science
In 2005, registered nurse and mother of four Jo Mousselli set out to solve a simple problem: giving modern women a way to look effortlessly beautiful without sacrificing their precious time. Drawing on nearly a decade of experience as a pediatric ICU nurse at Texas Children’s Hospital, she brought the same rigorous standards of hygiene, safety, and precision from the clinic into the beauty world.
Alongside her husband and family, Jo co-founded Xtreme Lashes® — pioneering the semi-permanent eyelash extension industry in the United States before expanding to over 50 countries worldwide. Today, the brand is stocked in prestigious retailers like Saks Fifth Avenue and Spa Nordstrom, and is recognized as the world’s most trusted name in lash extensions and lash-compatible cosmetics. Every product is designed with one promise: to enhance your natural beauty without compromising the health of your lashes.
Your Lash-Safe Beauty Lineup
Each Xtreme Lashes product is specifically formulated to work with — not against — eyelash extensions, while delivering professional-grade results for natural lashes too.
GlideLiner™ Long Lasting Eye Pencil
A Beauty Launchpad Reader’s Choice Award winner, the GlideLiner marries the precision of a liquid liner with the effortless glide of a traditional pencil. Its silky, vitamin E-enriched gel formula applies without any tugging, then sets into a smudge-proof, fade-resistant finish in just 20 seconds. Available in 9 rich shades — hypoallergenic, dermatologist-tested, and 100% vegan and cruelty-free.
Lash Densifying™ Liquid Eyeliner
This innovative dual-tipped liquid eyeliner does double duty. The fine Precision Tip fills gaps along the lash line for a naturally fuller look, while the angled Style Edge Tip lets you craft a flawless winged liner with ease. Enriched with lash-nourishing peptides — it actually nurtures your lashes as you wear it. Available in Classic Black and Dark Brown.
Length & Volume Mascara
Featuring a large, lash-maximizing brush designed to coat each lash from root to tip, this mascara delivers dramatic length and volume in a single swipe. Its color-rich, vitamin B5-enriched formula creates high-impact definition and separation — all without clumping, flaking, or smudging. Waterproof and fully compatible with eyelash extensions.
The Perfect Eye Routine
Define & Sharpen
Always begin by sharpening the GlideLiner with its dedicated sharpener for a clean, precise tip. Using short, light strokes, apply along the lash line from the inner corner outward. Let it set for 20 seconds, then replace the cap tightly to keep the gel formula fresh.
Fill & Intensify
Shake the Lash Densifying Liquid Eyeliner first, then rest your elbow on a flat surface for a steady hand. Use the Precision Tip to fill any gaps along the lash line for a denser look. For an evening look, switch to the Style Edge Tip to create a confident wing. Store horizontally to keep both tips evenly saturated.
Amplify & Lift
Sweep the mascara brush from the base of your lashes upward in one fluid motion, coating every lash from root to tip. Apply a second coat for extra drama while the first is slightly tacky. If you wear lash extensions, focus application only on your natural lashes.
Remove Gently
Saturate an Xtreme Lashes Flex-Tip Applicator with the brand’s Eye Makeup Remover & Facial Cleanser and gently wipe across the lash line. Rinse with water, pat dry, and groom your lashes with a Retractable Lash Styling Wand to keep extensions looking their best.
Getting the Most from Your Lashes
Smoky Eye Upgrade
After applying the GlideLiner, blend and smudge with an angled brush around the 10-second mark — before it fully sets — for a soft, sultry effect.
Day-to-Night Switch
Use the Precision Tip of the Lash Densifying Liner for your daytime look, then add the Style Edge wing in the evening to transform it into a statement look.
Extend Wear
Always push caps firmly closed after each use. Store the Lash Densifying Liner horizontally so the liquid formula stays evenly distributed across both felt tips.
Extensions First
With lash extensions, focus mascara only on natural lashes or their base. Always use Xtreme Lashes’ oil-free cleanser — avoid oil-based removers near extensions.
